“…According to [1], increase of (002) reflection in relative intensity is consistent with formation of ZnO rod crystallites along c-axis. In [2][3][4]6] judgment, such preferential growth in the (001) plane results in 1D nanostructure of ZnO arrays, e.g. nanowires, nanorods or nanopillars, that grow along the direction perpendicular to the substrate.…”

“…Now highly transparent conducting ZnO windows are important components of photovoltaic devices and displays. Recently, solar cells with extra thin absorbers (ETA SC) have shown high potential of ZnO arrays as semiconductor covered electrodes and dye-sensitized photoanodes, particularly, ZnO nanorods proved to be suitable for application in organic photovoltaic devices [5,6]. An assortment of ZnO nanostructures, such as whiskers, nanowires, nanorods, nanotubes, nanorings and nano-tetrapods have been successfully grown via a variety of methods including chemical vapor deposition, thermal evaporation, and electrodeposition.…”

“…low processing cost, large scale, no vacuum system need, high deposition speed and no use of toxic gases. Effects of electrolyte formula, namely anionic composition [4] and presence of the different organic additives [6], deposition temperature and deposition time [7] and even gravitational level effects [9] on structure and properties of the electrodeposited ZnO nanowire arrays are studied extensively. Nevertheless, there are only rare attempts to employ a pulsed potential technique for ZnO electrodeposition [10].…”

Abstract:The feasibility of one-dimensional (1D) nanostructured zinc oxide array pulse plating has been presented. An effect of the electrolyte composition, deposition regime and subsequent annealing on structure and optical properties of the electrodeposited ZnO layers has been approved by X-ray diffraction and spectrophotometric analysis. We have determined that for obtaining of ZnO arrays with strong (002) preferable growth orientation in the c-axis direction it is necessary to diminish adsorption of hydrogen and Cl --ions. It has been shown that such conditions are created in electrolyte that contains 0.05 M Zn(NO 3 ) 2 and 0.1 M NaNO 3 during electrodeposition on FTO-coated glass substrates in pulse plating regime with rectangular impulses of cathode potential (20 ms on-time at U on = -1.4 V and 30 ms off-time at U off = -0.8 V). Therefore, in this work we for the first time have demonstrated the successful growth of 1D ZnO nanostructures by pulse plating without using of templates. The novel electrodeposition technique gives possibilities for the manufacture of the ZnO arrays suitable for solar cells with extra thin absorbers.

“…In particular, controlling the optical and electrical properties in ZnO films is important for optoelectronic applications such as solar cells and flat panel displays [3][4][5][6]. For example, the electrical properties of ZnO can be changed from semiconducting to metallic by extrinsic doping (e.g.…”
